Possible options for Geea.

Hey there geea. I'm sorry I couldn't make it down to show you around Nizpro as I had hoped, however by the sounds of it Simon took some time out of his hectic schedule to give you a rough idea of the things that happen in his 'small' but equally impressive workshop.

As suggested in your post, let's keep this thread on the straight and narrow, something I believe you would have noticed is the only way I play the game these days. In turn the following a my response to your questions and other comments I have read so far on the thread.

You mentioned the Ferrari. For the record, it is an F355 being equipped with a custom fabricated twin turbocharged set-up. You may have also noticed a Veilside body kitted 350Z also lying around? Well, it too is being fitted with a twin turbo combination; requested by the owner who after going for a drive in a 350Z that Simon had already equipped with a similar package, just had to have it. He couldn't believe that a car could go so incredibly hard and yet idle like a pussycat, and be driven comfortably to the local shops by a grandmother.

Geea, these are the sorts of things that Simon (Nizpro) is all about. And this is why people entrust him with $300,000 cars.

Likewise, as Bcl as explained, Simon is the owner of DynoLogic, a chassis dynamometer company building leading edge products containing software that - right now - is years ahead of anything else on the market.

The OBD2 port interface allows him to view every single parameter in the Ford ECU (literally many many thousands). In other words, why do you think the Cobra kits incorporate the custom plenum and the other 160 or so bits? Because development on the engine and chassis dyno - with the assistance of the world's best dyno software as well as OBD2 - provides him with more number crunching and analysis ability that any other company in this country.

Geea, you are one of the few who has now seen just a glimpse of the things that go on at that little place called Nizpro.

You touched on power at various boost levels comparing two different brands of product. Once again it is as a consequence of development that has resulted in good power at low boost levels hence no need in up to around 310-320 rwkw levels for valve springs. Why? Because the lack of boost dictates that the valve is not pushed open as boost rises.

You also mentioned an old turbo6 dyno sheet. Noted elsewhere in the forum (under the SA cruise from memory), turbo6 told how his car was put up against a Phase 3 from a local workshop with a resultant 317 rwkw for the Cobra Stage 2 and 315 rwkw for the APS Phase 3. Both of these cars are going to be taken to the drag strip for further comparison. My point being that with the Stage 2 you can achieve the 320rwkw level - if so desired - however Simon prefers to keep the numbers lower for the sake of keeping the internals in one piece!

You also alluded to a secret;

(I can't say any details (I think they know where I live), but , bloody hell it was truely amazing. Maybe Cuspub can elaborate abit more when he is able).

Well, it's no big secret really, taking up space in Nizpro's engine dyno cell is a stock stroke XR6 Turbo engine with the same internals as Bcl's, most of the normal Stage 2 bolt on pieces including the plenum, and with custom Nizpro extractors and turbo.

A MoTeC ECU is there but has been problematic with the manufacturer currently looking at modifying their software to solve the problems. As a consequence, development (tuning) has stopped at the moment. Mind you, Simon only pulled the plug once he has turned the wick up to 18 psi (he plans on taking it to around 23psi), with Optimax fuel and to 6500rpm. He's happy with the result of 850 horsepower at this level, but concerned that the lack of MoTeC control is keeping a lid on things.

Once the MoTeC software is sorted, the engine is given another 5 psi of boost and the revs are pushed to 7500, expect in excess of 1000hp.

Talking engine internals. I can only suggest, however I feel incredibly confident, that Nizpro knows more about these engines than any other shop in the country; their weaknesses, strengths, where to modify, how to modify, what to change, what to add, and so it goes. Toying with workshops that are merely looking at replacing pistons and rods is a long way from solving potential problems.

Finally, my thoughts on intercoolers I believe are born out in the earlier comments surrounding research. By combining a quality intercooler that isn't so large that it interferes with radiator cooling, with a properly sized and flowing plenum et al, you end up with a product capable of delivering exceptional power at low boost levels.

Thanks for your post geea.

That new intercooler should also see a healthy drop in those high intake temps you are recording, let us know what they drop to when the IC is installed.

Hi Greg,

what would be involved in fitting your low-piping solution for a bigger intercooler to a car that runs an aps kit?

[fordboy1981]

it would be good if NIZPRO offered it's intercooler on it's own...that would be perfect for you Craig...

We have no qualms supplying a Nizpro intercooler on its own, the problem is adapting it to suit the rest of the combination.

I was actually talking to Lachlan (chiptorque), about this. I was saying that the Nizpro kit looked great and sounded fantastic. I also mentioned how I have used Amberley so far and was very happy and impressed with their work. Lachlan said to me "why dont you get Amberley to fit the parts of the Cobra kit that you need".

This would be the perfect solution for me. I'm going to wait and see the intercooler that Amberley is developing. I will then compare this with the Nizpro kit. I may even be able to utilize parts of both.

I won't be doing this for a few months as I am in the middle of building a new club and its keeping me broke. Hopefully though I'll be able to get the IC problem sorted before summer. I really think the "T's" will feel the heat when the warmer weather hits.

The problem with that theory, Geea, is that there needs to be a large change the to the plumbing of the xrt with either the nizpro or aps kits. You need to work out which is better for you, but it's no small job that's for sure

[xlr8ed]

great thread craig, I did get 270rwkw@11psi with phase II and phase III will be on by saturday, but looking at the intercooler I cant see the weather changing performance on the car..its bloody HUGE.. ive got a new mod for you its a 2 inch block of timber that mounts under you accelerator pedal so you can stop going so damn QUICK!!!

p.s the block is also available in alloy.(colur coded to your vehicle) $10 extra :lol:

Why wouldn't you use the APS cooler? How many $$$$$$ are they?

I didnt say I wouldnt. I just noted that it appears the nizpro unit achives the same results as the aps unit while using less boost because it uses less plumbing from the intercooler to the engine. Less plumbing = less heat = cooler air = better power from lower boost.
